Be it known that I, HE RY'E. Anew, a citizen of the United States, andresident of -Milwaukee, in the -county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in ControlMechanism; and I do hereby' declare that the following is a full, clear,and exact descri tion thereof.

- is invention relates to improvements in control mechanism and is moreespecially nism which may be actuated either by fluid pressure. ormanually.

Qther objects and advantages will be apparent from the followingdescription read in connection with the accompanying draw' in s, inwhich i gure 1 1s a side elevation of the device. with parts shown insection, and parts of a locomotive shown diagrammatically 1n 1connection therewith.

Figure 1 is an illustration of the indicator dial used in connectionwith mydevice. I r

Figure 2 is a vertical sectional viewtaken on the line 2 2 of Figure ,1.

Figure 3 is a vertical sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a vertical sectional view taken on the line 44 of Figure 2.

Figure 5 is a. horizontal taken on the line 5-5 of Fi sectional view re3. u

' Figure 6 is a vertical sectional view taken diagrammatically ,in-Figure 1v and desig-.

nated by the reference character L. To this gure 8 is a detail sectionalview taken frame is attached the supporting bracket 10, I

to which are attached the bearing members 11. The reversing lever 12. ispivotally mounted in said bearing membersand is .60

provided with an arm which is pivotally connected to the reach rod 13. Agear segment 14 is also carried by said levenconcentric with its pivot.

A casting 15 is mounted on the locomotive,

and is provided with a transverse flange 16, to WhICh are securedbearin'g' members 17. Within these bearing members are journaled thetrunnions 18 which carry'the bearing block 19 in which is journaled thereduced portion" 20 of the longitudinal shaft 21. This longitudinalshaft is provided with a worm-22 which is engageable with the gearsegment 14. The opposite end; of the shaft 21 is journaled in a block 23which is slid- "73 in ably -mounted in a vertical guide-way. 24, whichis carried by the casting 15. .The reduced portion 20 of the shaft 21 isconheated by a universal joint 25 with the tele- I scoping r'od26vwhich! is in turn connected so with the rod 27. The rod 27 extendsupwardly andrearwardly to thecabwhere it is provided with a hand wheel28 'by-which it may be rotated. The wheel 28 is also provided with a'ratchet 29 which is engageable by the pawl 30 to hold it in any positionto which it may be'adjusted.

The slidable block 23 is connected by a piston rod 32 to the piston head31 which operates within; the cylinder 33 carried by V the casting 15.Thus it will be seen that when the piston head 31 is carried upwardlyfrom the position shown in' Figure 1, the worm 22 will be disconnectedfrom the re,-

versing lever 12 and the manual operation 05 thus rendered inoperative.The reversing lever 12may also be rocked by means of the rod 34, which.is ivoted at one end thereto. The opposite en of the rod 34 ispivotallyconnected to the piston rod 35, on the end of which-the head 36 iscarried. The piston head '36 operates within the cylinder 37 whichisattached to the frame of the locomotive. r

The rod 35 is provided at the end which is connected with the rod 34with a bracket 38,

. which is mounted to slide on the guide 39. .Thepiston heads 36 and 31are adapted to be reciprocated within the respective cylinders by fluidpressure. controlled by means located within the valve box 40,v which isattached to the locomotive by the bracliet's 40 and 40". Said valve boxis provided with encloses the' cylinder the bore 55.

the vertical central channel 41 with its two branches 41 and 41". Thischannel is in communication with the atmosphere through the port -12,which may be provided with the pipe 42". extending to a point outside ofthe locomotive.

The upper side of the channel 11 is separated by the plates 43 and =11from the channel 45, which is connected by the inlet 46 to a source offluid pressure. The two branches of the atmospheric channel 11* and 4:1are separated by the casing 1-7 which 18. Said cylinder may be placed incommunication with the upper part of cylinder through theopening 49 andthe pipe 50. The cylinder 48 may be placed in communication with thelower end of the cylinder through the opening 51 and the pipe 52. Theupper 'end of the cylinder 48 is also provided with a. port 53. openinginto the atmospheric channel. Reciprocally mounted within the cylinder48. is the fluid control member .51 which is provided with the' centrallongitudinal bore 55 and the transverse openings 56, and iscircumferentially reduced as shown at 57 and 5S.

With the fluid control member 51 in the position shown in Fig. :2. theupper end of cylinder 33 will be in-communication through the pipe 50and opening 49 with the channel 45 which is under pressure. The lowerportion of the cylinder 33 will be in communication through the pipe 52and opening 51 past the reduced portion 5Tand through the port 53' withthe atmosphere. The piston head 31 will. therefore. be held in theposition shown in Figure 1.

When the fluid control .member 54: is raised by means hereinafterdescribed. its

upper end will pass the opening 49 and shut oil the same from thepressure in the channel 45. The opening 19 will then be placed incommunication with the atmosphere through the port 53, past the reducedportion 57.

Atlthe same time the opening 51 will be cut ofi from the atmosphere andplaced in communication with the pressure in the channel 45 by means ofthe opening 56 and The piston 31 will then be raised to the upper limitof" its movement and the worm 22 disconnected from .the gear segment 14.

The valve casing is also provided with a vertical cylindrical cavity 59.which is in communication through the opening 60 and pipe 61 with oneend of the cylinder 37. The valve casing is also provided with anothervertical cylindrical cavity 62 which vis in communication through theopening 63 and pipe 61 with the opposite end of the cylinder 37. Both ofsaid cavities 59and 62 are provided with ports 65 opening into theatmospheric channel 11. Each of the cavities 59 and 62 is normallyclosed at its upper end by the valve 66 mounted on the valve rod 61'.which is'reciprocally mounted at its upper end in the, bearing member65. said valve being held yieldingly on its seat by the spring 69. Thelower end of the valve rod 67 is .slidabl'y mounted in the plunger 70.hen the plunger is raised by the rock arm 71 it will first cover theport 65. After this port has been covered. the lower end of the recess72 will strike the lower end of the valve rod 6? raising the valve 66and admitting fluid pressure from the channel 15 into the cavity 59 andthrough the opening 60. the pipe 61. into one end of the cylinder,communication of" this end of the cylinder having been previously cutoff from the atmosphere by the closing of the port 65.

In a similar manner when the member T1 is rocked in the oppositedirection. the other end of the cylinder will be cut off from theatmosphere and opened to pressure. the pressure within the cylinderoperating to force the plunger downwardly until the pressure fluid isallowed to escape through the port 65 to the atmosphere. The movement ofthe plunger T0 in the downward direction, is limited by the stop 73 asshown in Figure 3. The rock arm T1 is mounted on the rock shaft 7- whichis journaled in the bearings 75 and T6 attached to the walls of thevalve casing.

The shaft 74 is rocked by means of the lever 77 which cooperates withthe segment 78 which is frictionally engaged by the spring pressed pawl'T 9. Said rock shaft 71 is also provided with a crank 80 on which iscarried a plate 81 which engages the member 5% when said shaft isrocked.

The bracket 38 is connected at its upper end with the spherical bearingmember 87 through which projects the arm 86 which is mounted on thelower end of the rod 85. said rod being connected through beveled gears8:1: to the rod 83 which is operatively connected to the indicator onthe dial 82.

The operation may be briefly summarized as follows:

With the parts in the position shown in Figure 1, both ends of thecylinder 37 are in, communication with the atmosphere. The lower end ofthe cylinder 33 is in communication' with the atmosphere and the upperend thereof under pressure. In this position the reversing lever 1:? maybe freely operated and held securely in any position by means of thehand wheel 28. If it be desired to operate the lever 12 by fluidpressure. the lever 77 is rocked forward or backward according to whichway it is desired to swing the lever 12. This movementrocks the shaft 74and no matter which way it is rocked the first result will be to raisethe fluid control member 54. This results in opening the upper end ofcylinder 33 to the atmosphere and'opening its lower end to pressure ashereinbefore described. This results in raising one end of the shaft 21and disconnecting the worm 22 from the gear segment 14, and leaves thelever 12 free to be operated by the piston head 36.

The further movement of the lever 77 and shaft 7 4 results in raisingone of the valves 66 and subjecting one side of the piston 36 topressure, this end of the pylinder having been previously shut ofl fromcommunicationwith the atmosphere by closingthe port 65. The position ofthe lever 12 will be indicated on the dial 82 as will be readilyunderstood.

I have described and illustrated my in- \ention as applied to alocomotive, but it will be understood that the invention 18 not limitedto the precise structure herein shown A and described, or to theparticular adaptation thereoflbut that it covers all equivalents andmodificatidns which may fall withpivoted member,

in the scope of the appended claims.

I claim as myintentionz l 1. In combination, a pivoted member, a gearsegment thereon concentric .,with its pivot, 'a manually operable wormengageable with said gear segment for oscillating said -means operableby fluid pressure for disconnecting said worm from said gear segment,means operable by fluid pressure for oscillating said pivoted member,and valves for controlling the admission of fluid pressure to each ofsaid'pressure operated means successively.
